I COTTON-PIGKERFOR FORMING MATTRESS-BATS.

SPECIFICATION forming part of Letters Patent No. 698,535, dated April 29, 1902.

Application filed April 26, 1898. Serial No. 678, (N m 7 i for Forming Mattress-Bats, of whichthe following is a specification.

My invention is an improved machine for [O straightening the fibers of lint-cotton and picking the same, and it is especially adapted for use in connection with a machine for making cotton-batting for mattresses, the f u nction of my present improvement being to so I prepare the cotton that the same-when compressed into mattress-batswill be light and H will be rotated at amuch higher rate of elastic.

My invention consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointed out in the claim. a

In the accompanying drawings, Figure 1 is a side elevation of a straightening-machine embodying my improvements. Fig. 2 is a top plan View of the same. Fig. 3 is a vertical longitudinal sectional view of the same,taken on a plane indicated by the line a; w of Fig. 2. A suitable frame 1 is provided at one end with an inclosing case 2, having a hinged secing 4 on its lower side,the size of which open;

ing may be varied by a slidingboard L,which is supported and is adapted to be moved on guides 5. A delivery-spout I is on the outer side of the said casing, and in the lower side of the casing, on one side thereof, is an inclined board I,which is disposed between the opening 4 and the innerend of the spout I. In the casing, at one. side thereof, is disposed a picker-roller F, which is journaled in the sides of the casing and is provided with peripheral spikes or pins, which in practice are about half an inch long and are placed about half an inch apart. The said picker-roller is 5 disposed under the hinged section 3 of the top of the casing. A blast-cylinder H is located at one side of the picker-roller between the latter and the discharge-spout I and immediately above the board I, said blast-cylinder being provided with peripheral blades G,

which coact with the pins or spikes of the picker-roller, as will presently appear. A pulley'6 is placed on one end of the shaft of the picker=roller, and the opposite end of the said shaft has a driving-pulley 7,which may be 5 5 driven by a suitable source of power through an endless belt. (Not shown.) The blast-cylinder has a pulley 8 on one end of its shaft, which is proximate to the pulley 6 of the picker-roller and is very much smaller than said picker-roller, and beyond said pulley 8 is an idle guide-sheave 9. Anendless belt 10 connects the guide-sheave 9 and pulley6, and the lower lead of saidbelt passes also over. the upper side of pulley 8, and hence when the picker-roller is rotated the blast-cylinder speed. In practice the blast-cylinder makes about fifteen hundred revolutionsin a minute.

, A pair of feed-rollers E, which are longitudinally corrugated and are disposed in en gagement with each. other one above the other, are located adjacent the outer side of the picker-roller F, and said feed-rollers are pro vided at one, end of their respective shafts with connecting-gears 11 12.

:An endless traveling feed-apron 13 is hori zontally disposed in the frame 1 and is sup ported and actuated by rollers 14. 15. The roller 15 is provided atone end of its shaft with a spur-wheelld and a spur-pinion 17. The latter engages an idle gear-wheel 18, which meshes with the gear 12 and communicates motion to the lower feed-roller from the roller 15, motion being communicated to the upper feed-roller by the gear 11, which meshes with gear 12. The gear-wheel 16 engages a pinion 19 on a shaft 20, which shaft is provided with a pulley 21. The said pul= ley being rotated by an endless belt imparts 9 motion to the endless traveling feed-apron and to the feed-rollers through the gearshere inbefore described. A series of condenser rollers B are disposed on the upper side of the endless traveling feed-apron and of suitable weight, the-journals of said rollers being disposed in vertical slots D in the sides Gof that portion of frame 1 in which the endless feedapron is disposed.-

In operation the raw cotton is placed on the loo f inbefore referred to.

inder H is such that the blast created by the "blades'thereof draws the cotton from the picker-roller F and throws it downward endless traveling feed-apron, passes under the condensing-rollersB, the coaction of said endless traveling feed-apron and said condensing-rollers being to form a hat of the cotton, which bat passes between the coacting corrugated feed-rollers E and from the same to the picker'roller F, said feed-rollers preventing and holding the end of the bat to .the 'action of the picker-roller, the spurs or pins against the board I. The cotton lint is then caught on the board I by the said blades, which act mechanically to beat the cotton along the board until it passes beyond the action thereof, when it is caught up by the airblast and pneumatically carried through the spout I. Hence the cotton lint is repeatedly acted upon pneumatically and mechanically and the fibers straightened and cleaned. The sliding board L serves to regulate the strength of the air-current by varying the size of the air-intake opening 4 of the inclosing case.

By means of the hinged section 3 of the top of the inclosing case the'picker-roller may be uncovered when desirable.

Having thus described my invention, I clairn a y In a machine of the class described, the combination of an endless traveling feedapron, rollers thereon coacting therewith to form and feed abat, an inclosing casing having a feed-opening on one side, a deliveryopeniug on the opposite side provided with a spout, an air-inlet bottom opening and an inclined board between said air-inlet opening and said delivery-opening, feed rollers to which the bat is delivered and located in said feed-opening, a picker-roller coacting with said feed-rollers to draw the bat therefrom, disintegrate the bat and draw the fibers therefrom, and a revoluble blast-cylinder disposed in operative relation to the picker-roller, on the side thereof opposite the feed-rollers and over the said inclined board, said blast-cylinder having peripheral straightening-blades to draw the fibers from the picker-roller and beat the same on and along the inclined board, and create a blast to carry said beatenv and straightened fibers through said dischargespout, substantially as described.
